Is there a program that will provide a visualization for any audio output? [closed]

Is there a program that will provide a visualizer for any arbitray audio output? Basically, I want to play Pandora at a party and supply some funky visualizations to go with it. Pandora either uses Adobe Air or its own Flash application, so I can't stream it through Winamp or something similar. I'd really prefer not to jerry rig it using an extra audio cable either.

For what it's worth, I'm on Windows 7. I heard Vista+ did funky things with the audio stack, so I figured I might as well get that out there.

Solution 1:

Check the screensaver application from http://www.plasmavis.com/faq.html or search an alternative visualization based on microphone input, this might allow you to select Stereo Mix or use a microphone with you place behind something. It might have a funny effect that the people will see their voice in the visualization at some quiet point. xD

Solution 2:

Try the interactive music visualization program (real-time) on this site.

It works by any displaying of sound file on a Windows (at least) computer. The program is interactive, real time and includes many essentially different variants. As I can judge it provide much greater correlation with music signal that other music visualization programs.

Solution 3:

Open winamp and click on the visualization drop box at the top right side. Left click anywhere in the black area. Hold shift and L and type linein:// in the window that pops up and press enter.

Solution 4:

Winamp makes it easy... the above post about it makes it a bit confusing...

Open the browser to the site and start playing the stream.
Open Winamp
Click Options | Visualizations | Start Plugin (Visualizations is actually listed twice on this drop down menu, click the top on, my version its the 3rd one down).
You will get the visualization window on screen... click it and then press the key combo CTRL+L
An input window will popup, enter "linein://" without quotes into it and click OK.

... visualizations will start reacting to the stream. Right click and choose Fullscreen mode and enjoy!
